'Specification of Letters Patent. Application fled March 1.2, 1910. Serial No. 548,895,

Patented July 15, 1913.

' which the following is'faspecication, and` whichare illustrated in the accompanying i drawings,'for1ning a partthe1eo-f.

The, invention relates to improvements l1nvwindows, and more particularly to windows havingl metal frames and sash, though some 'of its 'features are 'applicable to wo od" conf4 struction.-

within the sash, and' an improved sash guide'.

' The invention .is hereinafter fully de! dow frameand a pair'of sash; Figs. 3, 4A

and 5 aredetail plan sections of the sash retaining mechanism.

Preferably the sash is of sheet metal, be-

showing various modiliatio-ns ofthe sash' ing formed of inner and outer plates l0, 11,

which may be united 'at their 'outer edges, vas by means of a lchannel barl2 fitted between .them and" to which they fare'I riveted, -the out-er margins 'of the plates being folded inward to form a? stileeengaging face. 'The inner marginal portion of one ofthe plates,

as 10,v is inclined inward toward the glass 46to form a suitable-bead or finish 13, and then bent outwardtoward the edgeof'the sash to form a shoulder 14 against which the flat face of' the glass may rest, and then again bent -to form a seat 15 perpendicular to the side facev of the sash for receiving 'the `edge of the glass 16.` The other 'side plate 11 terminates on a'line with thefirst fold of inwardly, as shown 4at 17.1 A4 retaining plate 1 8'is fitted to theouter surface of the offset portion ofthe plate 11, its inner margin being bent or inclined inwardly toward the glass and then folded outward, as shown at 19, to form a flat face for engaging the flat surface of the glass.

A staying,- bar 2O isv fitted within the The objects oftheinvention are to provide improved means lfor securing the glass housing for the springs 26.v

chamber ofthe sash, being applied Aand pref erably soldered to the inner face of the 'plate' 10. This bar may, .as in Figs. 1 and 2, be of sheet metal stamped orfolded to channel form. One wall of the bar engages the glass seat 15 and holds the same rigid.

l The plates 10 and 11 are secured together bymeans of'telescoping screws'21, 22, which are set 'through the bar-20 and around which are coiled expanding springs 23. The glass havlng been placedfagainst theshoulder 14 and seat 15, the retaining strip isfitted in place and the screws 21, 22, setup to draw the A parts firmly against theglass, The retaining stripA 18 being of sheet metal, gives "slightly upon the application of -screw pres- `sure and, while securing the glass firmly in place, 'holds it with a yielding pressure.

In ltheconstruction illustrated in Fig.- 3,

there is substituted for the stay bar S0, as shown m Figs. l andV 2, a solid-bar 24. having its inner face eounterbored Vtoy provide ape1 V tures for the retaining screws' 25 and-a In the construction illustrated in Fig. 4, the sash rail 27 is shown as of wood, sho-uh so i dered at 28 t'o provide a suitableiseat for the .l

glass' 1'6. Y The face of the rail, opposite the 'shoulder 28, is cut away, as shown at 29, ,and 'tthis portion is coveredby a metal plate 30, secured tothe woodby means of screws 31. The inner margin of the plate30 is .offset inwardly, as vshown at 32, and to this offset rail, including` the'plates 30 and 33, and 'draw the vlatter snugly against the glass. The wood member 27 of the rail' is counter.- bored to accommodate `the screws and spring.

I n the construction illustrated in Fig. 5,

the sash 'rail 37is of wood. and is provided with the usual seat 38 for the. glass. Its face opposite this seat is cut away, and to this cut-,away portion there is applied a folded retaining plate 39, one leaf 40 of the plate lying against 'an inclined surface of therail 37 and its other leaf being folded inward to bear againstthe glass 16. The retaining plate secured tothe sash-railby means of screws 41.

The stile of the window frame shown at 42. To this stile are suitablysecured guidestops 43, 44, here shown as of sheet portion is applied 'alretaining strip 33, folded inwardly to engage the glass 16. Telescoping screws 34, 35, are set through the metal. Intermediate of these stops there is fixed to the stile 42 a longitudinal bar 45,

preferably of metal, this bar being secured to the stile plate by means of screws, as 46.

V`surface of the stile plate 42. These folded portions 48, 49, o'f the plate form yielding stops coperatvi'ng with #dre stopsr4r33 44to provide runways for a pair of sash. The outstanding portions of the plate 47 afford a guide-Way for a dust screen.V Y

I claim as my invention-l l. In a Window sash, in combination, a rail having a shoulder seat for a light of glass, a flexible retainingstrip for holding' springs resisting the compressive action of the screws.

j 2. In a window sash, in combination, al

rail having side plates of Hexible sheet metal, one of such 'platesheingbent to'fo'rni Y v a shouldered seat fora light of glass, YaV retaining strip bearing upon the outer face of the other plate 'for holding the glass totheshoulder,`a spring resisting. the compressive act-ion of the screws, a stay member secured tothe inner'face of the first-named plate and supporting the seat, and screws for advancing the retaining strip2 the stay being sock- 35 eted to receive the spring.
